How do I find my Model Number?
Do you have the original packaging?
-
If your product came in plastic packaging (a clamshell), you’ll find the model number on the front of the insert card, on the lower left corner. If your product came in a box, you’ll find the model number on the top of the box.
Most model numbers are 12-16 characters and start with a couple letters followed by a dash.

No packaging? No problem!
-
The product number is on a label on the side of the dimmer or switch.*
If you’ve already installed the dimmer/switch, turn off the electricity and then remove the wallplate. Unscrew and remove the wallplate adapter, then unscrew the dimmer/switch and pull it out of the wall until you can see the label.
*Please note: The product number for Ariadni/Toggler dimmers is not on a label. It’s located directly on the front of the dimmer on the top left, or right below the on/off toggle.

Can I set a preset level for the lights to come on to when I enter the room?
Yes. Simply set the dimmer to the preferred light level. Then hold the "Test" button on the sensor for 6 seconds until the light behind the sensor starts blinking. The lights will now turn on to the set level whenever the room becomes occupied.
-
Are sensors automatically configured when added to a RA2 Select system?
Yes, like Pico remotes, sensors are automatically configured to control the lights in the room that they are added to. By default, the system will use the following programming:
- Occupied - all lights will go to 100%
- Unoccupied - all lights will go to 0%
-
What sensor programming can be manually adjusted in the Lutron app?
The app allows for adding/removing lights affected by an occupancy group (and changing levels of each affected light) for both occupied and unoccupied actions. This includes setting occupied and/or unoccupied actions to "unaffected" for each individual light.
-
Can I add multiple sensors to a room?
Yes, if multiple sensors are added to the same occupancy group (a RA2 Select room), they will work together using occupancy group logic:
- The room will be set to occupied when the first sensor in the room detects occupancy.
- The room will stay occupied until every sensor in the room no longer detects occupancy.
- Can a sensor control a light in a different room?
- Can additional sensor timeout periods be added in the app?
-
What settings can be changed on the sensors themselves?
The following settings can be changed by using the programming buttons found on the sensors.
- Auto-on
- Enabled
- Low-light: The sensor will perform the occupied action only if the turn is relatively dark; if the room is bright, the lights will not turn on.
- Disabled
- Sensitivity level (described as ""Activity"" on the sensor).
- Timeout (1, 5, 15 and 20 min options)
- Auto-on
- What devices can be controlled via occupancy programming?
